Auger electron charge transfer

Nevertheless, the one-electron approach does have its deHciencies, and we believe that a major theoretical effort must now be devoted to improving on it. This is not only in order to obtain better quantitative results but, perhaps more importantly, to develop a framework which can encompass all types of charge-transfer processes, including Auger and quasi-resonant ones. To do so is likely to require the use of many-electron multi-configurational wavefunctions. There have been some attempts along these lines and we have indicated, in detail, how such a theory might be developed. The few many-electron calculations which have been made do differ qualitatively from the one-electron results for the same systems and, clearly, further calculations on other systems are required.

Figure 3.25 Potential energy diagrams representative of (a) resonant charge transfer (RI = Resonant Ionization of a neutral atom and RN = Resonant Neutralization of a positive ion), (b) Qnasi-resonant charge transfer (qRN = quasi-Resonant Neutralization of a positive ion) and Auger charge transfer (AN-Auger Neutralization of a positive ion). The dashed arrows represent electron transfer from populated to vacant electron levels, whereas the horizontal lines represent the allowed electron levels, otherwise referred to as stationary states.
